Question

determine o conjunto da solucao considerando u=Q
a)7w+3=2w+23

b)2(3p+1)=11

c)2y/3-y=2-2y/3

d) m+m/7=40

e)3(2x+3)=7x-2

Answer 1

8a) 7w+3=2w+23
7w-2w=23-3
5w=20
w=4

b) 2(3p+1)=11
6p+2=11
6p=11-2
6p=9
p= 3/2

c) 2y/3-y=2-2y/3
2y-3y=6-2y
-y=6-2y
-y+2y=6
y=6

d)m+m/7=40
7m+m=280
8m=280
m=35
